Java Olingo Jersey配置“未找到默认构造函数”

我正在尝试遵循本教程:https://www.baeldung.com/olingo 在教程代码中,JerseyConfig类只有一个带有2个参数的构造函数,但这会导致“无默认构造函数错误”

如果我添加一个默认的构造函数,那么该项目将正确构建,但是显然参数化构造函数中的代码不会运行,并且在尝试查询时我只会得到404

public JerseyConfig(CarsODataJPAServiceFactory serviceFactory, EntityManagerFactory emf) {


System.out.println("************* JERSEY CONFIG MAIN ***********************");
    ODataApplication app = new ODataApplication();

    app
      .getClasses()
      .forEach( new Consumer<Class<?>>()
{
    @Override
    public void accept(Class<?> c)
    {
          // Avoid using the default RootLocator, as we want
          // a Spring Managed one
          if ( !ODataRootLocator.class.isAssignableFrom(c)) {
              register(c);
          }
      }
});

    register(new CarsRootLocator(serviceFactory)); 
    register( new EntityManagerFilter(emf));
}

相关错误:

 org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.baeldung.examples.olingo2.JerseyConfig]: No default constructor found; nested exception is java.lang.NoSuchMethodException: org.baeldung.examples.olingo2.JerseyConfig.<init>()
